Abstract
A starting system for an internal combustion engine automatically operates a starting feature on a carburetor associated with the engine. The starting system includes a cam with a bearing mounted on the crankshaft. The bearing is secured so that its inner race will always rotate with the crankshaft. The cam has bosses on one side and is shaped such that it includes a base and a lobe with an outer surface surrounding the cam. At least one spring-loaded pawl is mounted on the flywheel. The pawl is biased to engage a cam boss so as to cause the cam to rotate with the crankshaft during a start-up process. A spring loaded rocker arm is pivotally mounted adjacent the cam. The rocker arm has a roller assembly configured to ride on the outer surface of the cam. As the cam rotates, the roller assembly riding on the cam surface is pushed outward by the cam lobe. A throttle cable is attached at a first end to the rocker arm and at its opposite end to the starting feature on the carburetor. When the roller assembly ramps up the lobe, the throttle cable is pulled into an extended position to actuate the starting feature of the carburetor.
